Spectrum-3-SN4000, Nvidia Ethernet Switch, Spectrum-3/SN4000

The NVIDIA Spectrum-3-SN4000 is a high-performance data center Ethernet switch family designed for modern enterprise and cloud fabrics. Built on the NVIDIA Spectrum-3 ASIC, this switch platform delivers up to 12.8 Tb/s switching capacity with low latency and deterministic performance, ideal for large-scale leaf/spine architectures. It supports flexible interface speeds from 1/10/25/40/50/100/200/400 GbE, allowing operators in Asia, Europe, Africa, and North America to standardize on one platform while upgrading links step by step. The Spectrum-3-SN4000 is designed for high-performance data center Ethernet fabrics where consistent throughput and predictable behavior are critical for virtualized workloads, storage traffic, and AI clusters.

For distributors and value-added resellers, the Spectrum-3-SN4000 offers a scalable Ethernet switch family that fits a broad range of rack designs, reducing portfolio complexity and easing stock management. Small and mid-size integrators can use the same platform to build leaf/spine networks for private cloud, colocation facilities, or regional data centers while meeting strict SLAs. Enterprise end users benefit from a stable, standards-based switch that integrates smoothly into existing IP architectures and supports gradual migration to higher port speeds as demand grows.

The Spectrum-3 ASIC architecture is engineered to preserve line-rate performance even under mixed and bursty traffic, supporting congestion management and fair bandwidth allocation across tenants and applications. This makes the Spectrum-3-SN4000 well suited for data center consolidation, hybrid cloud connectivity, and latency-sensitive services. The platform’s flexible role as a leaf or spine switch gives network teams a unified building block for both access and aggregation layers, simplifying design and operations. Whether deployed in cloud services, enterprise IT, telecom, or research environments, the Spectrum-3-SN4000 helps deliver predictable performance, efficient east–west traffic handling, and future-ready 400 GbE connectivity.
